Definitions

  • the present invention relates to a recording medium support apparatus that supports a roll-shaped recording medium at both end portions thereof and a recording apparatus including the recording medium support apparatus.
  • Examples of a recording apparatus that records an image on a recording medium based on image information include a printer, a copying machine, a facsimile machine, and the like. Further, examples of the recording apparatus includes a multifunction peripheral including other functions such as a printer function, a facsimile function, a document reading function, and an image capturing function and a system device including the recording apparatus connected to a host device such as a computer.
  • An exemplary recording apparatus used in these apparatuses uses a recording medium in a state that a sheet, e.g., a recording medium or a film, is rolled up (hereinafter referred to as the “roll sheet”).
  • the above described recording apparatus uses a sheet conveyance apparatus for feeding and conveying a sheet from a roll sheet holding unit which holds a roll sheet to an image formation area.
  • the “sheet” in the present invention refers to a recording medium.
  • a material of the “sheet” is not limited to paper or a plastic sheet.
  • a long shaft (which is referred to as the “spool shaft”) which includes flanges at both end portions thereof is passed through a center of the roll sheet and the flanges and rotationally supported by bearing units of a main body of the roll sheet holding unit.
  • the flanges is configured so as to be slidable over the spool shaft according to a width of the roll sheet.
  • the above described configuration requires a longer spool shaft as the roll sheet width becomes wider and a wider working space when the spool shaft is inserted into the roll sheet. Therefore, workability is not so good in the above described configuration. Further, a hollow iron tube or a hollow aluminum tube is typically used as a material of the spool shaft when a weight of the roll sheet is taken into consideration. However, as the spool shaft becomes longer, not only a cost of the spool shaft becomes higher but also a weight of the spool shaft becomes heavier. Accordingly, the workability becomes worse.
  • Japanese Patent Application Laid-open No. 11-322141 and No. 2007-261754 discuss a configuration of a roll holder without the spool shaft.
  • the apparatus discussed in Japanese Patent Application Laid-open No. 11-322141 has a configuration that flange members fit to a core tube of the roller sheet are only suspended on the bearing units of the main body, so that the flanges tend to tilt due to a weight of the roll sheet. If the flanges tilt, a rotational center of the roll sheet may be shifted to cause a skew feeding of the roll sheet.
  • the apparatus discussed in Japanese Patent Application Laid-open No. 2007-261754 has a configuration that the flange members are rotatably supported by the main body of the apparatus and the bearing of one of the flanges is slidably supported in a width direction of the roll sheet such that a width of the bearing is adjusted to a width of the roll sheet.
  • the issue of tilting flanges is somewhat relieved.
  • the roll sheet is installed to the apparatus, while the core tube of the roll sheet is fit to one of the flange members, the other one of the flange members is slid to be fit to the core tube.
  • the other one of the flange members is required to be moved in the width direction (i.e., in an opening direction), even in a case where a width of the roll sheet is not changed.
  • the present invention is directed to a recording medium support apparatus capable of reducing a rotational resistance of a roll sheet and improving a working efficiency in installing the roll sheet, and a recording apparatus which includes the recording medium support apparatus.
  • a recording medium support apparatus capable of reducing a rotational resistance of a roll sheet and improving a working efficiency in installing the roll sheet, and a recording apparatus including the recording medium support apparatus can be provided.

  • the roll sheet Pr includes a recording medium made of recording paper or a plastic sheet formed into a continuous roll shape. That is, a material of the roll sheet Pr is not limited to paper.
  • the roll sheet Pr is conveyed by the LF roller 6 that is positioned at an upstream side of the recording unit 5 as a conveyance unit.
  • the recording unit 5 is provided with a platen 7 for supporting the recording medium from a rear surface side of the recording medium.
  • the platen 7 is configured to guide the recording medium such that a gap is formed between a recording surface of the recording medium and the recording head 2 .
  • the recording head 2 is configured to record an image while the recording head 2 is moving along the main rail 4 .
  • the recording medium is conveyed in a conveyance direction by the LF roller 6 by a predetermined pitch. While the recording medium is conveyed by the predetermined pitch, the recording head 2 is moved again to record an image of the next line.

Insertion of the fitting portions 20 Ra and 20 La into the corresponding end portions of the core tube Prp of the roll sheet Pr enables the fitting portions 20 Ra and 20 La to fit into the core tube Prp.
  • the roll holders 20 R and 20 L include flanges 24 , respectively.

Further, because edges of the leaf springs bite into the core tube Prp, better gripping can be realized. Still further, the leaf springs 25 and 26 are arranged along a line in an inserting and withdrawing direction, so that not a large operability is required.
  • a roll gear 27 is installed to the flange 24 formed on the roll holder 20 R. Rotation of the roll sheet Pr is controlled by a below described roll driving unit via the roll gear 27 .
